CLEANING AND DISINFECTING POWDER FOR THE REMOVAL OF STAINS,-

INCRUSTATIONS, 8:0.

No Drawing.

To all whom it may concern Be it known that I, LEO A. Ma'r'rns, a citi- Zen of the United States, residing in Berkeley, in the county of Alameda and the State of California, have invented a new and useful cleaning and disinfecting powder for the removal of stains, incrustations, and disagreeable odors found in many Waterclo'set bowls, of which the following is a specification.

The incrustations and stains usually found in water-closet bowls are due to certain calcium, magnesium and iron salts deposited from the water standing in the bowl from time to time, and the urine after standing a short time deposits some of its chemical constituents as well.

The accumulation of these deposits results in the water-closet bowl. becoming very unsightly, unsanitary, and oftentimes emitting a disagreeable odor, and the object of my invention is to provide a convenient means for removing these objectionable features in an easy and safe manner. This point is attained by the use of a dry powder, resulting from a thorough mixture of two to three parts of dry powdered sodium pyrosulfate with one part of dry sodium chlorid. T his powder when sprinkled into the bowl, in which there is Water, and allowed to stand for a few minutes, and by slightly rubbing and flushing the bowl, will Specification of Letters Patent.

leave the bowl in a clean and white condi tion. By the use of this powder I claim vast improvement over the use of hydrochloric acid or other like acids, as the acids are dangerous due to their strong caustic action, and hydrochloric acid emits 0bnoXiousfumes which are irritating to the eyes and nostrils, and also due to its strong caustic properties it is damaging to the vessel on which it is used. l/Vherein by the use of the powder the above objectionable fea-- tures are overcome. The sodium pyrosulfate in itself is a good solvent for most of these deposits, but in conjunction .With sodium chlorid and in the presence of water, a chemical reaction takes place, in which better results are obtained. s

It is not my intention to limit the scope of the invention to the particular proportions of the ingredients set forth, as the quantities may have to be modified to attain the best results with varying conditions as found.

I claim:

A cleaning and disinfecting powder resulting from the mixture of sodium pyrosulfate and sodium chlorid, substantially as described, and for the purpose specified.
